A steering assembly including an inner steering member; an outer steering member; a leaf spring disposed between the inner steering member and the outer steering member and adapted to bias the inner steering member, wherein the leaf spring comprises an inner portion and a plurality of outer portions, wherein the outer portions comprise end portions of the leaf spring that are folded over such that the outer portions overlie the inner portion, forming a folded edge; and a low friction layer supported by the leaf spring.

A supporting apparatus for a steering gear box includes a pressing yoke part for supporting a side surface of a rack bar to be engaged with a steering input gear in a shape to wrap the side surface of the rack bar, a supporting yoke part provided in a mounting groove together with the pressing yoke part, an elastic link part formed of an elastic material and extending from the pressing yoke part to be inserted into the supporting yoke part, a cover part provided at a position opposite to the supporting yoke part and shielding an inlet of the mounting groove, and a pressing part located between the supporting yoke part and the cover part and pressing the supporting yoke part by a predetermined elastic force.

A vehicle steering assembly comprises a steering member with a rack portion having rack teeth, a pinion gear having pinion teeth configured to be engaged with the rack teeth, a yoke support assembly supporting the steering member in a housing, and a ball nut operatively connected to the steering member. The pinion gear divides the steering member into a first side having the yoke support assembly outboard of an area of engagement of the rack and pinion teeth and a second side having the ball nut. The yoke support assembly includes complementary convex and concave bearing surfaces configured to provide relative rotation between the convex and concave bearing surfaces. The yoke assembly also includes a spring member configured to produce a variable rate spring force to maintain an engagement between the rack and pinion teeth.

Embodiments of devices for converting continuous rotational motion into oscillating motion are disclosed herein. In one embodiment, an oscillation device can include an input shaft that rotates about a first axis, a portion of the input shaft defining an eccentric section that defines a second central axis offset from the first axis, a connector rotatably coupled around the eccentric section, an oscillating shaft offset from the input shaft that rotates about a third axis, and a pin coupled to the oscillating shaft and extending towards the connector. The connector includes a sleeve slidably receiving an end of the pin, and continuous rotation of the input shaft about the first axis causes an eccentric movement of the connector, and the eccentric movement of the connector oscillates the sleeve along the pin and oscillates the pin with respect to the oscillating shaft, thereby oscillating the oscillating shaft about the third axis.

A device for a steering system of a motor vehicle for pressing a toothed rack against a drive pinion is specified, the device having a housing and a thrust piece which is mounted displaceably in the housing and which has a circumferential wall which is in contact with the housing, the thrust piece having, on its circumferential wall, at least one depression which runs in a circumferential direction at least in certain portions and which delimits a hollow chamber arranged between thrust piece and housing.

The objective of the present invention is to reduce the impact of production variability in a radius of curvature of a rear surface of a rack bar, for example, while enlarging a region of contact with the rack bar. A concave surface (330) is used as a rack guide seat (32) sliding surface (33). In a YZ cross section perpendicular to an axial direction of a rack bar, the concave surface (330) includes: a pair of first arcuate surfaces (331A, 331B) which are disposed on a peripheral edge side (320) of the sliding surface (33), from two positions of contact TA, TB with a rack bar rear surface (22), the positions of contact TA, TB having line symmetry with respect to a straight Line O3 joining a center O of a rack bar (20) with a bottom portion center C of the sliding surface (33), and which have line symmetry with respect to the straight Line O3; and a pair of second arcuate surfaces (332A, 332B) which are disposed on a bottom portion side (321) of the sliding surface (33), from the positions of contact TA, TB, and which have line symmetry with respect to the straight Line O3. With regard to gaps to the rack bar rear surface (22) in positions separated by the same distance from the positions of contact TA, TB, the gaps from the first arcuate surfaces (331A, 331B) are greater than the gaps from the second arcuate surfaces (332A, 332b).

The present disclosure provides a rack bar supporting device of a steering apparatus for a vehicle. The rack bar supporting device includes: a support yoke to support a rack bar; a first cam member configured to have a front surface supporting the support yoke toward the rack bar and to have a rear surface provided with a first cam surface inclined in a circumferential direction thereof; a second cam member configured to have a front surface provided with a second cam surface inclined in a circumferential direction thereof to correspond to the first cam surface, to have a rear surface to which one end of a torsion spring is supported and coupled; a yoke plug; and an elastic pin.
